Member Function Documentation

◆ dump()

void BESShowContextResponseHandler::dump ( ostream &  strm) const
virtual

Displays the pointer value of this instance

Parameters
strmC++ i/o stream to dump the information to

Reimplemented from BESResponseHandler.

Definition at line 106 of file BESShowContextResponseHandler.cc.

References BESResponseHandler::dump().

◆ execute()

void BESShowContextResponseHandler::execute ( BESDataHandlerInterface dhi)
virtual

Context in the BES refers to name/value pairs set in the BES to help direct the operation of the BES. For example, there might be an error display context, an error context, a response context (make them all silent), a test run context (don't actually execute the commands, just go through the motions). This response handler knows how to retrieve the list of context name/value pairs.

Parameters
dhistructure that holds request and response information

BESDataHandlerInterface
BESInfo
BESContextManager

Implements BESResponseHandler.

References BESInfo::begin_response(), and BESContextManager::list_context().

◆ get_name()

virtual string BESResponseHandler::get_name ( ) const
inlinevirtualinherited

This name is used to determine which response handler can handle a requested response, such as das, dds, ddx, tab, info, version, help, etc...

Returns
response name

Definition at line 156 of file BESResponseHandler.h.

◆ get_response_object()

BESResponseObject * BESResponseHandler::get_response_object ( )
virtualinherited

Returns the current response object, null if one has not yet been created. The response handler maintains ownership of the response object.

Returns
current response object

BESResponseObject

Definition at line 53 of file BESResponseHandler.cc.

◆ set_response_object()

BESResponseObject * BESResponseHandler::set_response_object ( BESResponseObject o)
virtualinherited

This method is used to replace the response object with a new one, for example if during aggregation a new response object is built from the current response object.

The caller of set_response_object now owns the returned response object. The new response object is now owned by the response object.

Parameters
onew response object used to replace the current one
Returns
the response object being replaced

◆ transmit()

void BESShowContextResponseHandler::transmit ( BESTransmitter transmitter,
BESDataHandlerInterface dhi 
)
virtual

If a response object was built then transmit it as text using the specified transmitter object.

Parameters
transmitterobject that knows how to transmit specific basic types
dhistructure that holds the request and response information
